  • Falcataria Moluccana Molucca Albizia Fabaceae
    Falcataria moluccana Molucca albizia Fabaceae Forest Starr, Kim Starr, and Lloyd Loope United States Geological Survey--Biological Resources Division Haleakala Field Station, Maui, Hawai'i January, 2003 OVERVIEW Falcataria moluccana has been widely planted throughout the world for ornament and reforestation. It was first introduced to Hawai'i in 1917 by Joseph Rock (Little and Skolmen 1989). In Hawai'i, F. moluccana has been planted by the hundreds of thousands for ornament and reforestation. Trees are attractive and the wood is useful for a variety of things from furniture making to canoe building. However, trees are spreading from initial plantings to adjacent pastures, forests, and disturbed areas. Because of its widespread distribution throughout the state coupled with its popularity, perhaps the best approach currently would be to control the tree in certain sites where it is not wanted, such as natural areas, pastures, and farmland. Seeds tend to fall nearby and trees do not disperse over a long distance (miles), except when people move the tree to a new area. If this dispersal trend were to change, such as if a vector to spread the trees further arrived or if it was planted again on a grand scale to new areas, the tree may become a bigger problem. TAXONOMY Family: Fabaceae (pea family) (Wagner et al. 1999). Latin name: Falcataria moluccana (Miq.) Barneby and Grimes (Herbarium Pacificum Staff 1998). Synonyms: Paraserianthes falcataria (L.) I. Nielsen (Wagner et al. 1999), Albizia falcataria (L.) Fosberg, A. falcata (L.) Backer (Little and Skolmen 1989). Common names: Molucca albizia (Little and Skolmen 1989). Taxonomic notes: There seems to be a lot of name changing and rearranging that has occurred within this complex.

This study aimed to (1) experimentally test the response of sengon seedlings in waterlogged conditions in the nursery; (2) describe and analyze the biophysical condition of a sengon plantation and its growth; (3) describe sengon farm practices on peatlands; and (4) identify key actor’s perception on planting sengon on peatlands. This study combined an experiment in nursery, field measurements, and key-informant interviews. The nursery experiment showed that peat soil affected seedling’s growth: survival rates decreased by 25–33% after 3 months of inundation. Sengon growth at age 1–5-years-old in peat soil was slower than that on mineral soils. Sengon growth in peatland was influenced by peat depth and peat maturity.

  • Islander Perceptions of Invasive Alien Species: the Role of Socio- Economy and Culture in Small Isolated Islands of French Polynesia (South Pacific)

Islander perceptions of invasive alien species: the role of socio- economy and culture in small isolated islands of French Polynesia (South Pacific) Islander perceptions of invasive alien species: the role of socio- economy and culture in small isolated islands of French Polynesia (South Pacific) J.-Y. Meyer1 and M. Fourdrigniez2 1Délégation à la Recherche, Government of French Polynesia, B.P. 20981, 98713 Papeete, Tahiti, French Polynesia. <[email protected]>. 2Groupement Espèces Envahissantes, Bioconsulting, B.P. 50902, 98716 Pirae, Tahiti, French Polynesia. Abstract Islands, often celebrated as natural laboratories for evolution and ecology, also provide unique experimental grounds for societal studies. Although biological invasions are widely recognised as one of the main causes of biodiversity erosion and a driver of global change, the human perception of invasive species may vary at regional and local levels, especially in societies with different levels of socio-economic development and cultures. This study was conducted in French Polynesia (South Pacific), a territory formed by 120 tropical and subtropical oceanic islands (76 being inhabited) divided into five archipelagos (Austral, Marquesas, Society, Tuamotu, and Gambier Is), comprising both highly populated and urbanised islands (such as Tahiti in the Society Is) and less populated and very small islands, sometimes very isolated (without airstrips) and where traditional life style and strong dependence on natural resources still persist. During an eight-month education and prevention campaign targeting alien plant and animal species legally declared invasive in French Polynesia, public meetings were organised on 19 small islands for a total of 2,045 consulted people in 41 different villages.

  • Albizia Biological Control Project Overview
    Albizia biological control project overview - FY2018 Kenneth Puliafico & Tracy Johnson Institute of Pacific Islands Forestry, PSW Research Station, USDA Forest Service Albizia (Falcataria moluccana) is one of the most economically menacing and environmentally destructive tree species to be introduced to Hawaii and several other Pacific Island nations. Despite several million dollars expended annually on mechanical and chemical control, invasions across Hawaii and the Pacific are already so widespread that long term management will depend on biological control using host-specific natural enemies. Albizia biocontrol has been prioritized by the interagency Hawaii Invasive Species Council and been supported by the US Forest Service, USFS – International Programs Office and the State of Hawaii. One of the most exciting recent developments in our project has been the start of the molecular DNA analysis of Falcataria moluccana. IPIF technician Nancy Chaney began working with Dr. Jessica Wright, US Forest Service - PSW Davis and their colleagues at the University of California – Davis for two weeks in November & December 2017 on the initial analysis of plant samples from over 200 sites. During the very short time working together 148 samples of DNA representing 130 populations were extracted and 93 of these samples produced PCR product suitable for sequencing. Our goal is to compare the sequences of trees collected in Hawaii with those from the native range in Indonesia, East Timor and Papua New Guinea. This is an essential step for modern biological control programs because finding the source of the invasive population allows us to find the location of the most highly coevolved natural enemies to select as future biological control agents.

  • March 18, 2013 RE: Testimony to State
    March 18, 2013 RE: Testimony to State Senate Committee on Energy and Environment Dear Sir or Madame: Aloha. Please note that I am submitting testimony in strong support of SCR 74 and SR41 entitled, “Urging the Department of Agriculture to add the albizia tree to its noxious weed list and urging the invasive species council to develop and implement a comprehensive interagency plan for the control and eradication of albizia on the island of Hawaii”. This resolution is sorely needed. I include the following documentation of the management issues surrounding this fast-growing and hazardous tree. Invasive alien species have caused untold damage to the ecology and economies of areas they have invaded (Elton 1958). Where invasive species introduce new biological processes or disturbance regimes into ecosystems, they have the potential to profoundly alter both community characteristics and ecosystem functions, often to the extreme detriment of the native flora and fauna being invaded (Vitousek et al. 1987, D’Antonio and Vitousek 1992). The invasive alien tree, Falcataria moluccana (Miq.) Barneby and Grimes (synonyms: Paraserianthes falcataria (L.) I.C. Nielsen, Albizia falcataria (L.) Fosberg, Albizia falcata auct) is a very large, fast-growing, nitrogen-fixing tree in the legume family (Fabaceae) (Wagner et al. 1999). It is a daunting invasive species, in that it is considered to be the fastest growing tree species in the world, capable of growing ca. 2.5 cm in height per day (Footman, 2001, Walters 1971). Further, individuals reach reproductive maturity by the age of four years and subsequently produce copious amounts of viable seed (Parrota 1990) contained within seed pods that are wind-dispersed and can be carried substantial distances (i.e., > 200 m) up- and down-slope during windy conditions.
